Question Monitor Problems

Wondering if anyone can help me with my monitor. It tends to flicker a little when I bring it out of 'sleep' mode, and sometimes it will just go blank after about thirty seconds of operating. After that, I spend another half hour turning the thing on and off, restarting the PC, etc. to try to bring it back to life. Eventually, it comes back (for no identifiable reason), but I'm thinking that either there is a short that I could fix if I knew more about monitors, or it is just plain dying.

If anyone has had experiance with this or knows monitors, I would certainly appreciate some help.

Thanks.

Monitor

It's help to know what OS you're running, possibly upgrade your video drivers and/or lower the resolution to see if the refresh rates are too high.

To quote Jonnie-5 "Need more input."

OS = ? Vid card = ? Video onboard or seperate? Shared video memory?
Video settings; number of colors = ? Screen area pixels = ? x ?
Model/type of monitor? Is video cable securely attached to DB-15 plug? Power source firmly plugged into electrical outlet? Video card fully inserted into slot?

Sorry about the vague question.

I have a Gateway EV700 monitor. As far as I can tell, the problem is not with either the video cable or the power cable.

I have an integrated video card/motherboard (2Mb??), and later added a Voodoo PCI 2000 (at least 8 Mb, maybe 16 Mb??? - not sure, not at home). When I began having this 'blackout' problem, I uninstalled the Voodoo card and reinstalled all of my original Gateway video drivers.

As far as driver issues, I have done a complete reinstall of Windows 98 (OE) twice since I got this system and have not had any problems with the current drivers in those instances.

So the only change to this monitor's environment was spending roughly a year on the Voodoo Card.

I honestly don't know much about refresh rates, etc. My current settings are 800x600, and 24 bit True Color, although I did spend some time set at 1024x768 with 24 bit True Color.

If you turn the monitor off for a few min does it come back on, or do you still have to play with it to get any results? You may have to take it in for service, may have a capacitor that is going bad. you might see if you can take the cover off and a can of air or 3 and blow off the circuit boards and any other areas that are collecting dust. Other then that, your only option is to take it in and have it serviced.

Where I work we buy a lot of Gateways. The EV700 does have issuse with power supplies and (correct me if I get the term wrong) flyback transformers. Basically, they can start shorting out on the inside. Another prob I've seen with this model is that they don't like coming out of sleep mode. Any chance you're still under the 3 yr warentee?

OK I'll bite on this one since I was a former Gateway Tech. The EV700 hates sleep mode with a passion unless you are running XP. Dont ask me why but the bloody thing works fine with XP's power management but not with the others. If it goes black and wont come back, unplug the power to the back of the monitor for 30 seconds and plug it back in and that should have you up and running again. If you continue to have the flickering and distortion on the screen I would contact support for a Replacement if its under warrenty. Some other things to look for as a potential problem with them is the monitor dimming over time and having to turn the contrast and brightness up to higher levels

Also a note: If you open the case of the monitor that will definately void the warrenty from Gateway. You can look for the dust buildup in the ventilation slats of the monitor and used compressed air to try and clean out but do not open that case...besides even unplugged a monitor has enough stored juice within it to knock you on your rear if it doesnt outright kill you first. Dont open a monitor unless you have the tool to discharge the electrical buildup on it

Thanks, Tarenger.

Sounds like you know exactly what I am talking about. Also, I caught the same shock warning in a manual I was perusing at the bookstore this weekend. At that point, I decided that I will try deal with sleep mode problem, and leave any repair work to the professionals.

sounds like a sound (and safe) idea. Being one who thinks "if its broke fix it" or "if it can be modified or made better, try" or my favorite "bheh, I can fix that!" If you dont have a discharge rod do not attempt to dishcharge the tube with your arm. Purposely or accidental hurts like a SOB and cant use your arm for a few minutes. After that and a few incidents with a 240 power panel, 120v is a welcome reminder.
